They had a string of top three singles including Bring It All Back, S Club Party and Don't Stop Movin. They became S Club in 2002 when Paul left, and then split up in 2003.

Jo, Bradley and Paul reformed S Club in 2012, and Rachel revealed the rest of the band have not ruled out a reunion.

Rachel told ITV's Lorraine: "We keep in touch, I haven't seen them for a while but we're always texting and tweeting and keeping in touch... It's always bubbling in the background talking about us getting back together."

There have been rumours S Club 7 will be taking part in the next series of ITV's The Big Reunion.

Rachel said: "Obviously it hasn't happened yet because I think getting seven diaries together is really difficult, everyone's off doing their own thing but it would be fun... I think if it was going to be, it would have to be all of us!"
